Abstract
This study introduces the development of a flexible and compact radiator using a jeans material as a substrate for wireless body area network (WBAN) applications. A fabric made of jeans with a thickness of 0.6 mm, a tangent loss (tan δ) of 0.02, and a dielectric constant (εr) of 1.6 is used for designing an element with dimensions of 18.5 × 27 × 0.6 mm3. The jeans substrate incorporates a triangular feed structure on top and a defected ground structure on its back. This design enables a span ranging from 3.41 to more than 20 GHz, with a magnitude of S11 < —10 dB, a peak gain of 4.48 dBi, and a peak efficiency of 97.28%. The system is designed for Ultra-wideband (UWB) integrated with Ku band. The measurement findings are very consistent with the results obtained from the models. The suggested antenna is highly appropriate for WBAN applications because of its thin profile, flexible design, and compatibility with WBAN and UWB technologies.
期刊介绍：
Radio Science (RDS) publishes original scientific contributions on radio-frequency electromagnetic-propagation and its applications. Contributions covering measurement, modelling, prediction and forecasting techniques pertinent to fields and waves - including antennas, signals and systems, the terrestrial and space environment and radio propagation problems in radio astronomy - are welcome. Contributions may address propagation through, interaction with, and remote sensing of structures, geophysical media, plasmas, and materials, as well as the application of radio frequency electromagnetic techniques to remote sensing of the Earth and other bodies in the solar system.
